The Anatomy of a Micropitting-Induced Tooth Fracture Failure - June 2010

The article "The Anatomy of a Micropitting-Induced Tooth Fracture Failure" appeared in the June 2010 issue of Gear Technology.

SummaryMicropitting has become a major concern in certain classes of industrial gear applications, especially wind power and other relatively highly loaded, somewhat slow-speed applications, where carburized gears are used to facilitate maximum load capacity in a compact package. While by itself the appearance of micropitting does not generally cause much perturbation in the overall operation of a gear system, the ultimate consequences of a micropitting failure can, and frequently are, much more catastrophic.
